Abstract

The oceans play a crucial role in the global ecosystem and offer solutions to meet the growing demand for food, water, and energy. However, a new economic concept is needed to regulate and sustainably exploit the maritime resources offered by the marine ecosystem to ensure sustainable development. It is in this initiative that the concept of the blue economy has emerged, in response to the inadequacy of measures taken by States to meet their obligations and achieve their objectives in terms of marine biodiversity conservation. This is how the blue economy concept was born, in response to the inadequacy of state measures to conserve marine biodiversity. This concept proposes an innovative solution integrating aquatic and human resources into sustainable economic activities. The aim of this study is to understand the opportunities and threats that the blue economy represents for innovative companies. This short literature review, based on a SWOT (Strengths, Weaknesses, Opportunities, and Threats) diagnosis of innovative companies, identified a number of obstacles to the development of the blue economy, such as climate change, lack of financing and the lack of instruments for measuring the performance of the blue economy. Action strategies could be implemented to mitigate risks, threats and hazards, and consider an economic approach that reconciles marine and terrestrial ecosystems.

Abstract

The most crucial aspect of managing an ecosystem or habitat is knowledge about accompanying biota, such as snails. The research on mangrove snails in the KPH Region III Aceh City of Langsa area was conducted in November 2021 with the goal of evaluating species diversity, density, ecological index, distribution, and their link to surrounding environmental conditions. Snail data was obtained via quadrat transects, with observation stations established using purposive sampling.The snail diversity was found to be five species from four families, with the highest density found in N. planospira (03.13 ind/m2). The diversity index was low (H' ≤ 2.0), dominance was moderate (0.5 < C ≤ 0.75), and uniformity tended to be balanced (0.5 < E ≤ 0.75). The distribution pattern is clustered (Iδ> 1), with C. cingulata being abundant (83.33%), and C. capucinus being frequently found (50.00%), N. planospiraonly found occasionally (36.11%), and L. scabra and T. telescopium are relatively uncommon (11.11% and 0.56%, respectively), with a link to environmental variables indicating that T. telescopium prefers fine mud substrates. Meanwhile, C. cingulata, C. capucinus, L. scabra, and N. planospiralive in habitats with fine mud substrates that are more solid than T. telescopium’s habitats.

Abstract

Seaweed is an important biological resource for human life, serving essential ecological functions, including providing shelter and feeding grounds for marine biota. Seaweed can be found in several Indonesian waters, growing naturally or through cultivation, including in the waters around Simeulue Island. This study aimed to assess the distribution of seaweed in relation to land suitability, using oceanographic parameters in Simeulue Island waters. The research was conducted at five stations within the West Teupah District, South Teupah District, and Alafan District. In situ measurements were taken to evaluate land suitability for seaweed growth based on oceanographic parameters such as current speed, depth, substrate type, salinity, temperature, pH, and dissolved oxygen. Results indicated that seaweed in Simeulue Island waters is distributed along the coastline and attached to coral reefs and rocks at depths of 2-5 meters. The total area of seaweed distribution is approximately 351.83 hectares along a coastline of 206.12 km. The measured parameters of seaweed habitats include a pH of 7.7 to 7.9, salinity of 31-35.3 ppt, temperature of 20-30 °C, dissolved oxygen levels of 3-4.8 mg/L, depth of 2-5 meters, current speed of 0.10 to 0.60 m/s, and a sandy coral substrate. Based on these water quality and substrate parameters, the seaweed habitats in Simeulue Island are classified as highly suitable, with suitability values ranging from 64 to 82. The recorded environmental conditions collectively support optimal seaweed growth.

Abstract

Water quality is one of several aspects that affect the success of aquaculture business. This study analyzes water quality and assesses its impact on aquaculture enterprises in the Rancong pond region of Lhokseumawe City. The study ran from November to December 2018. The water quality of the Rancong pond was sampled directly and tested in multiple labs. The field survey and purposive sampling strategy separated the research location into four stations with three water sampling points. Temperature, salinity, turbidity, brightness, pH, dissolved oxygen, alkalinity, total organic matter, BOD5, total ammonia nitrogen, nitrite, nitrate, phosphate, lead (Pb), total Vibrio bacteria, total general bacteria, and phytoplankton types and abundance were measured. The suitability of water quality is assessed using descriptive analysis, scoring, and matching. The investigation indicates that the quality and maintenance of the source water are highly suitable (S1). Traditional vannamei shrimp ponds in Rancong, Lhokseumawe City, should be maintained as fisheries cultivation areas.

Abstract

Raja Ampat conservation area is divided into three zones: the core zone, the tourism zone, and the open zone. This region is crucial for sustainable fisheries and environmental management, yet it is under significant anthropogenic pressure. Accurate species detection is essential for inventory and diversity surveys, and environmental DNA (eDNA) methods have been shown to be more effective than conventional techniques. This study aimed to evaluate whether V9 primers could detect multispecies invertebrate compositions, assess community structure and contributions within each zone, and identify significant differences in invertebrate diversity among the zones. A total of 66 eDNA samples were collected from water and sediment columns across the three zones. Samples were extracted using the NucleoSpin™ kit (Macherey-Nagel) protocol, amplified with universal eukaryote primers targeting the 18S gene, and sequenced using Illumina MiSeq. Taxonomic analysis was performed using QIIME2 software and the SILVA database. The study identified 19 invertebrate species. The Shannon-Wiener (H') and Simpson (D) indices revealed greater species diversity in the core zone compared to the tourism and open zones. However, the Kruskal-Wallis test indicated no significant differences in species diversity across the zones. SIMPER analysis demonstrated a high percent contribution of species in each zone. This study highlights the effectiveness of eDNA methods for biodiversity assessment and offers valuable insights into invertebrate community structures within the Raja Ampat conservation area.

Abstract

Integrated Multitrophic Aquaculture System (IMTA) is a sustainable approach to aquaculture, utilizing ecosystem dynamics by integrating various species. This study examined the growth and survival of milkfish (Chanos chanos), tiger shrimp (Penaeus monodon), and oysters (Crassostrea spp.) in IMTA systems with different stocking densities. A 30-day experiment using a nonfactorial-completely randomized design with four treatments and three replications was conducted. The results showed that the implementation of IMTA had no significant impact on the survival rate of milkfish, tiger prawns or oysters in all treatments. However, important variations in growth parameters were observed. Milkfish and tiger prawns showed the highest weight and length gain in treatment B, followed by treatments A, C, and D. Similarly, oysters showed optimal growth in treatment B, followed by A, C, and D, based on weight gain, length, width, and shell thickness. Throughout the study, the physicochemical parameters of the water remained within acceptable ranges, thus supporting ideal growth conditions for the cultured species. These findings underscore the potential of IMTA to increase aquaculture productivity while upholding the principles of environmental sustainability. By optimizing stocking density and encouraging species diversity, IMTA presents a promising avenue for advancing integrated aquaculture practices, in line with the FAO's blue economy concept and ecosystem approach to aquaculture. Future research should concentrate on refining the IMTA system and evaluating its long-term ecological and economic consequences.

Abstract

Tropical marine environments are abundant and diverse; therefore, shark and ray research at fishing port PPS Lampulo, Banda Aceh City was carried out focusing on morphometric characteristics and differences based on multivariate analysis in July 2020 to identify sharks and rays that landed at fishing port PPS Lampulo, Banda Aceh City and determine their primary characteristics. The shark and ray samples used were from the Indian Ocean and the Malacca Strait and measured total length (TL), fork length (FL), and standard length (SL) for sharks and disc width (DW), TL, and disc length (DL) for rays. Principal component analysis (PCA) and discriminant analysis (DA) were performed on the morphometric data. The PCA analysis revealed that sharks and rays caught in Pelabuhan Perikanan Samudera (PPS) Lampulo, Banda Aceh City, can be divided into two distinct groups. The first group of sharks consists of species with large FL and SL morphometrics, namely P. kamoharai, C. plumbeus, P. glauca, and A. superciliosus. The second group of sharks consists of species with large TL morphometrics, specifically A. pelagicus and C. plumbeus. For the ray group, the first group comprises species with large TL and DW morphometrics, represented by A. ocellatus. The second group of rays consists of species with large DL morphometrics, namely P. sephen and H. jenkinsii. The results of DA revealed distinct differences in the size of sharks caught in the Indian Ocean and the Strait of Malacca, specifically in PPS Lampulo, Banda Aceh City. However, no significant differences in size were observed for the rays, regardless of whether their size was measured using DW, TL, or DL.

Abstract

The increasing use of mercury in the industrial sector poses significant risks to freshwater ecosystems and aquatic organisms. Milkfish (Chanos chanos), a widely consumed species, is now being reared in freshwater environments, raising concerns about mercury bioaccumulation and food safety. This study aimed to determine the median lethal mercury concentration for milkfish at 96 hours (LC50) in freshwater using an experimental approach and probit analysis. Five mercury concentrations were tested: 0 (control), 0 .110 mg Hg/L, 0.195 mg Hg/L, 0.347 mg Hg/L, and 0.618 mg Hg/L. The results indicated that mercury is highly toxic to milkfish, with a 96-hour LC50 of 0.147 mg Hg/L. Clinical symptoms observed included loss of reflex movements, irregular swimming, frequent surfacing with widened mouth and operculum openings, convulsions, and ventilation of the ram before mortality. These findings highlight the acute toxicity of mercury in freshwater milkfish and underscore the potential health risks associated with mercury contamination in aquaculture systems.

Abstract

The study was conducted between August and September of 2021 in order to determine the density, ecological index, distribution pattern, geographic distribution, environmental factors, and the relationship between hermit crabs and environmental factors. Hermit crabs were gathered using a quadratic transect and sample plots, while environmental variables were measured in situ. PCA and CCA multivariate statistics were used to determine the characteristics and correlation between hermit crabs and environmental factors. Hermit crabs were discovered to be comprised of two species (Clibanariuslongitarsus and C. infraspinatus) and one family (Diogenidae), with the highest density found in the C. longitarsus species (1.22 ± 0.57 – 4.68 3.53 ind/m2), diversity index is categorized as moderate (2.0<H’≤3.0), the dominance is low (0<C≤0.5), the distribution pattern is clustered (Iδ>1), the geographical distribution is abundant (>80%), and environmental factors are categorized as good. In addition, Stations I and II have high DO, TOM, mangrove density, C. longitarsus, and C. infraspinatus parameters, whereas Station III has high salinity, pH, and temperature, with salinity, mangrove density, and TOM being the most influential parameters on hermit crab density.
